Sunspots in February 1894

Rebekah Higgitt says.....
Having mentioned Maunder's interest in sunspots in yesterday's post, I checked The Astronomer Royal's Report to the Board of Visitors for 1894. This records that for sunspots, "the characteristic of the year [May 1893-May 1894] has ... been rather the great number of groups visible at the same time than the extent of any one of them". It was noted that "the groups of 1893 November and 1894 February were very large". Magnetic Observations were carried out by a different department, but they noted that, while this year in general saw much less magnetic activity than the year before, "there was a large increase occurring 1894 February, at the time of the great sun spot."
